[Merge] lp:~fboucault/address-book-app/startup_time into lp:address-book-app

[Florian Boucault]

The proposal to merge lp:~fboucault/address-book-app/startup_time into lp:address-book-app has been updated.

Commit Message changed to:

Reduced startup time (by 600ms on krillin):
- Bottom edge: delay compiling contact editor page.
- Load Icons asynchronously.
- Made all Components compile asynchronously when possible.

Made startup time overhead when lots of contacts in address book as small as possible
